Abstract
One new cinnamic imide derivative, named tribulusimide C (1), was isolated from the fruits of Tribulus terrestris, together with three known compounds, N-p-coumaroyltyramine (2), terrestriamide (3), N-trans-caffeoyltyramine (4). The structure of 1 was elucidated based on chemical analysis and spectral methods (IR, 1D and 2D NMR, HR-FAB-MS, EI-MS).
